      OverviewExtractionGenesis and types of nickel lateritesOre depositsSee also

      Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits).
      Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes. Hydrometallurgical processes include high pressure acid leach (HPAL) and heap leach, both of which are generally followed by solvent extraction electrowinning (SX EW) for rec

      Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in
